.eommonly made in rubber factories which require vulcanization. v

In the manufactureof a rubber shoe it is customary, 1n some cases, to assemble certain'parts of the shoe to form a closed upper,

,to mount the closed upper together with an 'insole upon a last, to last the margin of the upper over upon the insole, to attach the out-sole and then to subject the shoe to vulcanization, the general object of the present invention being to facilitate the rapid and accurate assembling of the upper for the purpose described.

'In one aspect the invention provides a method of assembling parts of a rubber shoe .to form a closed upper which comprises mounting certain parts upon one section of a suitable form, mounting otherparts upon another section, putting the sections together and thereby uniting parts on one section with parts on the other, and then removing the "assembled parts from the form. The illustrated method is concerned with the assembling of the upper of an arctic or so-called gaiter wrong side out. In carrying out the method the vamp foxing and the vamp are mounted upon a generally wedge-shaped section of the form, portions of the opposite edges of'the vamp being bent over upon a flat face of the section and fastened in place by a piece of tape. The quarter foxing and the quarter are mounted upon the other section of the form, portions of the opposite edges of the quarter being bent over upon a fiat face of the second section and'fastened in place by a second piece of tape. The sections are then pressed together wit-h their fiat faces opposed to each other, this pressure serving through the pieces of tape, to unite the bent-over portions of the vamp and quarter. Certain stays may then beapplied after which the lining is wrapped about the form over'the parts which have already been as sembled thereon. The upper at this stage has been completely assembled wrong side out upon the form with certain parts gripped between the adjacent fiat faces of the sections. In order to remove the upper from the formthe wedge-shaped section is pulled out so asto give access to the pieces of tape referred to above. These pieces are then cut and the upper removed from the ther section. out.

Referring now to the accompanying drawings Fig. 1 is a perspective of the closed upper of a ladiesarctic or so-called gaiters;

part of the lining having been broken away; Fig. 2 is a perspective of the sections of the sectional form in separated relation with certain parts of the upper mounted upon the sections; V Fig. 3 is a perspective of the formwith certain, parts mounted upon it, after the sections have been put together; and

Fig. dis a plan of alining which is the last part of the upper to be put in place upon the form.

Referring first more particularly to Fig. 1, the closed upper of the particular rubber shoe shown comprises a vamp 1 and a quarter 3 The upper isthen turned right side fastened together at two generally triangular localities 5. The upper portion of the quarter 3 hasan ornamental pattern and, in the finished shoe, is bent down to form a so-called cuff. Alongthe bottom of the vamp is the vamp foxing 7 and along the bottom of the quarter is thequarter foxing 9. On the in- I side of the vamp and quarter are two generally triangular stays 11, these stays being in per there is provided a form consisting of two sections and 17 which will be termed respectively the vamp section and the quarter section. The vamp section 15 is generally wedge-shaped, being wider at the top than at the bottom; and, extending from top to bottom, is a flat face 19 provided with a groove 21. The sides 23 are substantially fiat throughout most of their extent and merge nto a curved face 25. The quarter section has comparatively narrow ends and a wider middle portion. The sides 27 are substantially fiat throughout most of their extentand merge into two curved faces 29 which meet at 31. This section has a fiat face 33 corresponding to the flat face 19 of the vamp section, and is provided with projections 35 which fit into the groove 21 so that the sections may be slidably connected. The two ind .projectionsfio are provided with small holes 37, 39 which, when the sections are together register respectively with small holes 41, 43 in the vamp section 15 to receive pins sothatthe sections may be accurately brought together always in the same relation to each other.

The vamp section is provided with a socket 45 and a p n 47; and the quarter section is provided with a similar socket 4-9 and pin 51. Although the method of assemblin the parts of the up er may be practiced by hand and will be so c escribed, certain of the parts oftheupper may, if desired, be mounted upon the sections of the form or upon the comp ete form b means of a machine, not herein shown, at of the type of the lining mounting machine disclosed in application Serial No. 309,181 filed Sept. 29, 1928 in my name. In machines of this type the lining or other shoe part is laid flat upon a strap, said strap being yieldingly held taut in horizontal position over two Presser rollers which are yieldingly held close together but may be forced apart. The form, or one of the sections, is detach ably mounted above the strap upon a crosshead in a substantially horizontal position with the curved face downward; and then the cross-head is moved down whereupon the form, or the section. as the case may be, pushes the shoe part and the strap down be tween the rollers so that the shoe part is Wrapped about the curved face and sides or the fnrm and pressed into place. The socketc 45, 49 and pins 47, 51 are provided for the purpose of detachably mounting either section or the complete form upon the crosshead referred to above whenever it is desired to do so.

In assembling the parts of the upper. the vamp faxing 7 is mounted upon the vamp section 15 of the form in the position shown in Fig. 3. This foxing is made of unvulcanized rubber and hence will adhere to the form sufiiciently to retain its position. The ramp 1 is next mounted upon the section 15 in the manner shown so that it somewhat overlaps the loving 7, the opposite edges of the upper portion of the vamp beinp bent ver upon the flat face 19 and fastened together by a piece of tape 53 which is adhesive upon both sides. The quarter toxing 9 is mounted as shown upon the section 17 with its ends projecting somewhat be yond the flat face The quarter is then ioun ed in the manner shown so that it somewhat overlaps the foxing 9. the opposite edges near the top being bent over upon the Hat face 3;) and fastened together by a piece of tape It will be understood that the sections of the town may have. marlts upon themto facilitate the proper location of the vaiious parts of the upper.

' The sections of the form are now pressed together with the pro iecti;

into the groove 21 and the hat faces 19 and 33 substantially in contact. as shown in Fig. 31 \Vhen the sections are'thus pressed tonether. the two pieces of adhesive tape 53, are caused to adhere to each other as well as to any portion of the vamp or quartcr with which they come in contact, the

result being that the vamp and quarter are I united in the localities indicated at 5 in Fig 1. In order to strengthen this union. between the vamp and the quarter as well as to provide a stronger bellows in the tinishcd shoe, two triangular stays, one of which is shown at 11. are now applied. each stay extending partially over the quarter and partially over the vamp. The ends of the quarter 'foxing 9 are lapped over upon the vamp toning 7. trimmed, it necessary, and prrseed into place. i

If the vamp, and the quarter are made of suitable laminated sheet material. the assembled upper may now be complete. but llHl'HlllP. a lining is used. Such a lining of friction fabric is shown in Fig. 4. This lininsr is wrapped about the form and the parts ot the upper already mounted upon it as they appear in Fig. 3, the maror ns of the free edges 57. 59 of the lining being brought togethcr at the rear of the form and then tr mmed.

The upper, at this stage. has been com-- pletely assembled wrong side out upon the form. In order to remove it from the form. the wedge-shaped section 15 pulled out so as to ive access to the interior of the u per. The tapes are then severed and the upper thus freed from the other section of the form. The upper is then turned right side o t and is re dy to be used. as has been outlined above. in the manufacture i a rubber shoe.
